Description

technical field

[0001] The invention relates to a shaft hole cooling and lubricating system for cooling and lubricating a high-speed generator in a microturbine power generation system. Its technology belongs to the field of cooling and lubrication, and can be used for cooling and lubrication of miniature high-speed power generation systems in the aerospace field that are sensitive to weight and size and have serious heat generation. Background technique

[0002] In the field of aerospace, microturbine power generation systems have relatively strict restrictions on space and weight. Because the high-speed and high-power power generation system will generate a lot of heat during the working process; in the micro-ram turbine power generation system, in order to save space and weight, the distance between the generator and the turbine is relatively close, and a large amount of heat in the turbine will be transferred to the generator; At the same time, the continuous and stable...
